We extend our earlier work on X-ray source stacking in the dee p XMM-Newtonobservation of the Lockman Hole, to the2 Ms ChandraDeep Field North and the 1 Ms ChandraDeep Field South. TheXMM-Newtonwork showed the resolved fraction of the X-ray background to be∼ 80-100 per cent at. 2 keV but this decreased to only ∼ 50 per cent above∼ 8 keV. The CDF-N and CDF-S probe deeper, and are able to fill-in some o f the missing fraction in the4-6 keV range, but the resolved fraction in the 6-8 keV band… CONTINUE READING
